Searching for Bracewell Probes - part 1

Ronald Bracewell

Bracewell Probes were first discussed by Ronald Bracewell in a 1960 Nature paper. The basic idea is send robotic probes to solar systems that seemed promising, and these probes would sit and wait for millenia looking for signs of intelligent life in those systems, and should those intelligent creatures ever reach a certain measure of sophistication, then either radio home for instructions, or simply provide a library of advanced knowledge that would help these lowly beings achieve a kind of galactic citizenship.
that the "Superior Communities" would

Bracewell Probes still seem like a sensible way for superior communities to reach out in their galactic neighborhoods, whether their intentions are benign or defensive. Rather than guessing when to send probes to check out a suspect solar system, they simply strike out for all of them in the neighborhood, and then wait. Would their purpose be, as Bracewell conjectured, to enlighten us, or simply to alert the rest of the superior community that here there be uppity apes?
